Carbon and activated carbons have been halide modified through the mechanochemical incorporation of iodine. The effect of the processing and chemical modifications on the physical and electrochemical properties was examined. Distinct evidence was obtained to support significant structural and electrochemical modificat…
Thermal properties of benzoic acids carrying one or two semiperfluorinated alkoxy tails on the aromatic core have been investigated in binary mixtures with the non‐liquid crystalline bidirectional trans‐1,2‐bis(4‐pyridyl)ethylene. The hydrogen bonded complexes built from the complementary molecular species show a sign…
The possibility of obtaining corrosion inhibition efficiency from the Scanning Vibrating Electrode Technique (SVET) is investigated. Results are compared with those obtained by Electrochemical Impedance Spectroscopy (EIS) for the inhibition of iron and zinc with cerium nitrate and 1H-benzotriazole. Examples of good an…
In this paper the passive layer cracking process that occurs under tensile stresses and anodic polarization conditions on AA1050, AA5052, AA5056, and AA7005 aluminum alloys was examined by means of direct current (dc) technique, dynamic electrochemical impedance spectroscopy (DEIS), and acoustic emission (AE). Researc…
We report on the temperature dependence of electrical resistivity and Seebeck coefficient for the p-type (Fe1-xRex)2VAl system with compositions 0≤x≤0.06 in addition to the result of measurements of thermal conductivity at room temperature. While Fe2VAl (x=0) exhibits a semiconductor-like behavior in electrical resist…
New Cu-based P-type icosahedral quasicrystals have been observed in the ternary Cu–(Ga or Al)–Sc alloy systems. The Cu–Ga–Sc quasicrystal forms almost exclusively in a rapidly quenched Cu48Ga34Sc18 alloy, and has a six-dimensional lattice parameter a6D = 0.6930 nm. The as-cast alloy with the same composition contains…
Peptide-functionalized thin films exhibit significant potential for integration into implantable devices and cell-based technologies. A new type of neuroactive peptide-modified silica was developed using sol–gel reaction chemistry to produce thin films from four different peptide silane precursors. Peptide silanes con…
We have investigated the phase stability of two MAX phases, V3SiC2 and V2SiC, by means of first-principles total-energy calculations within the generalized-gradient approximation and the projector-augmented wave method. The theoretical bulk modulus of V3SiC2 is 219GPa, which is ∼17% larger than that of Ti3SiC2 (187GPa…
Raw cashmere samples collected from animals in China, Iran and Australia were measured for crimp frequency, crimp form, fibre curvature and other attributes. Eleven different forms of cashmere fibre crimp including straight cashmere fibres were observed. Different cashmere crimp forms appear related to different origi…
Tissue engineering might bear promising solutions for overcoming the limitations of biological and mechanical heart valve substitutes. The concept of heart valve tissue engineering bases on decellularized biological matrices, as removal of cellular components might reduce immunological reactions, which are thought to…
The Scheffé linear model and the Cox linear model are two first-order model forms commonly used for analyzing mixture experiment data. In a fitted Scheffé linear model, the coefficient for a mixture component is the predicted response at that pure component (i.e., single-component mixture). In a fitted Cox linear mode…
A novel tetrakis(terpyridinyl)porphyrin derivative and its Ru(II) complexes were efficiently synthesized using microwave enhanced synthesis and shown to possess photovoltaic properties. Transmission electron microscopy and selected area electron diffraction were used to investigate its nanowire self-assembly.
We report the detailed characterization of high quality vanadium oxide ( VO x ) nanotubes (NTs) and highlight the zipping of adjacent vanadate layers in such NTs formed on remarkable nanourchin structures. These nanostructures consist of high-density spherical radial arrays of NTs. The results evidence vanadate NTs wi…
This paper deals with the investigation of space charge accumulation dynamics in XLPE electrical insulation. In particular, very fast charge packets, i.e., having large mobility, are observed to be injected from both electrodes and to cross the insulation bulk, thereby contributing to heterocharge build-up at the oppo…
In this paper, rectangular shape complementary split ring resonators (CSRRs) with different dimensions are introduced to realize balanced composite right/left handed (CRLH) structure.As the dimensions of CSRRs is altered, the required series capacitance should also be modified and the propagation characteristics will…
The protonation mechanisms of the poly(amidoamine) (PAMAM) andpoly(propyleneimine) (PPI) dendrimers are clarified and related to their molecular structure. The overall proton binding isotherms can be interpreted in terms of a site binding model, which involves a limited number of parameters, and can be used to gain de…
An overview on recent developments in thermal interfaces is given with a focus on a novel thermal interface technology that allows the formation of 2-3 times thinner bondlines with strongly improved thermal properties at lower assembly pressures. This is achieved using nested hierarchical surface channels to control t…
For the first time, pore formation on n-InP͑100͒ has been carried out by galvanostatic treatments in acidic liquid ammonia at 223 K. Voltage oscillations correlated to a specific current line oriented pore morphology have been evidenced by scanning electron microscopy.Whatever the anodic charge, a constant pore depth…
Hydroentanglement is a versatile and relatively little explored method of bonding the fibrous web using high-pressure water jets. These nonwoven structures have an extensive range of applications–for example, wipes, carpet backing, filters, sanitary, medical dressings, and composites. Such applications require certain…
One of the main differences between low-pressure and atmospheric-pressure plasma treatments is that there is little moisture involved in the low-pressure plasma treatment, although moisture could exist at the wall of the vacuum chamber or react with the substrate after plasma treatment, while in the atmospheric-pressu…
